TSK · 1 John 2:4

They profess to know God but with their deeds they deny him, since they are detestable, disobedient, and unfit for any good deed.

If we say we have fellowship with him and yet keep on walking in the darkness, we are lying and not practicing the truth.

If we say we have not sinned, we make him a liar and his word is not in us.

If anyone says“I love God” and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.
